Areas affected...northwest MN and northeast ND

Concerning...Severe Thunderstorm Watch 450...

Valid 221610Z - 221715Z

The severe weather threat for Severe Thunderstorm Watch 450
continues.

SUMMARY...Marginal and isolated severe wind/hail threats appear to
be diminishing into early afternoon across northwest Minnesota and
northeast North Dakota. Sustained storm development farther south
appears unlikely until late afternoon or later.

DISCUSSION...Earlier convection has largely consolidated to one
sustained strong storm across far northwest MN, producing a recent
measured gust of 55 mph. This will pose a near-term threat until it
shifts across the international border. Weak and increasingly
elevated convection persists to its west across northeast ND. It is
plausible that a cell or two could intensify and produce marginally
severe hail before shifting into southeast MB. Sustained
surface-based storm development appears unlikely through at least
early afternoon along the southeast ND portion of the front, owing
to the pronounced EML across the warm-moist sector.
